ALBERT FRIEDLEY AND HERMAN F. VOSHARDT, OF CHICAGO, ILLINOIS.

ONE-PIECE SHEET-METAL GUTTER-CORNER.

To all whom 'it may concern:

Be it known that we, ALBERT FRIEDLEY and HERMAN F. VOSHARDT, citizens of the United States, both residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in One-Piece Sheet-Metal Gutter-Corners, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

The purpose of this invention is to provide an improved gutter corner made of one piece of sheet metal.

It consists of the features of construction shown and described as indicated in the claims.

In the drawings z-Figure l is a plan view of a sheet-metal-gutter corner embodying this invention for an exterior corner. Fig. 2 is a similar View of a gutter corner having the invention applied to an interior corner or rentrant angle. Fig. 3 is a section at the line 8 3 on Fig. l. Fig. A is a section at the line 4 4 on Fig. l, diagonally through the corner. Fig. 5 is a section at the curved line 5-5 on Fig. l, showing the edge which would appear at that section as if the curved plane of the section were straightened out and made to appear flat.

The gutter corner shown in this application affords a path for the flow of water around the corner, which is curved both at the inner and outer side and widens at the corner as compared with the direct courses leading to and from the corner. The rounding at the outer side is particularly useful to deflect the current without the abruptness which characterizes a corner angular or mitered at the outer side, and which tends to cause the waterV to overflow at the corner evenv when the quantity of water is not nearly sufficient to ll the gutter in straight courses.

In forming gutter corners of one piece of sheet metal, there is an excess of metal due to turning the corner and also to shaping the metal to form the hollow for the gutter cr trough-way, both vshapings,-that is, the

shaping in semi-cylindrical form transversely and the shaping for turning the corner horizontally,-necessarily entering into the problem and affectingthe distribution and amount of excess of metal to be taken care of in some manner. The simple method of disposing of the excess of metal when no attempt is being made to keep the structure Specification of Letters Patent.

in one piece and without such cutting of the metal as to require solder joints, is by mitering, and a very common mode of effecting the result without cutting is to form a initer corner by crimping into a close clenched fold the excess of metal which would be cut away to form an ordinary cut and soldered miter joint. It is also customary to make such gutter corners of one piece by two or more such crimped or closely laid folds disposing of the excess metal, suoli crimps being symmetrically disposed at opposite sides of a diagonal through the corner. In all these methods, however, it will be observed that the crimps'or closely clenched folds are liable to hold water and become rusted and constitute points of weakness, because, besides the fact that the water will go into the fold and remain there, the close pinching of the crimp tends to crack the metal and will very often actually crack it when the crack cannot be discovered, so that a leak will develop quickly at such crimp or fold. Also, any method of disposing of the excess which produces or requires a closely pinched crimp, even if it does not start a crack in the metal, will crack the surface coating of the galvanized metal or tin and expose the steel foundation metal to rusting.

The presentinvention avoids the defects and dificulties above pointed out, and in addition, produces an ornamental gutter corner, utilizing the excess metal for the purpose of ornamentation. In the drawings, the single piece of metal, A, is shown formed into a gutter corner in which the excess of metal, due both to turning the corner and to guttering or hollowing for the trough, is taken up in two groups of comparatively shallow corrugations, B and C, respectively, the former at the inner and the latter at the outer side of the corner. The corrugations of both groups radiate from points located in a line diagonal with respect to the corner, and all the corrugations diminish in depth toward the bottom or middle of the channel of the gutter, leaving the gutter substantially smooth at the middle bottom part. The shallowing of the corrugations as they approach the middle of the gutter is easily elfected, even though the amount of the metal to be taken up does not diminish uniformly at the rate at which the shallowing of the corrugations might be desired, because the corrugation may be widened as it is diminished in depth lfor taking up the amount of excess required by thev curvature in both directions. The result of this method of disposing of the excess is almost unavoidably ornamental, the two groups of radiating corrugationsY .naturally constituting the ornamental feainto a roll, D. hreferably, also, an exterior corner is finished to Aan angle, as seen in Fig. l, at the corner, E, although the channel of the gutter is curved for turning the' corner, the roll, VD, vbeing cut andv mitered, as will be easily understood, the slight soldered joint required for miteri'ng the roll at the corner, E, being unobjectionable because it is not Within the ytrough or channel. For an interior corner or rentrant angle, in which the roll, D, bounds a reentrant angle of the gutter corner', a similar' expedient rof mitering the roll may be resorted to Without departing from the requirement that vthe gutter proper, throughout the entire channel'thereof, shall be With-` out any cut or joint requiring soldering.

It Will be observed that the curving of the channel around the corner at the outer as Well as the inner side Which serves the? rent more easily than a mit'ered' or angular corner, is effected in a manner to avoid the necessity for disposing of a very large excess; of metal in the ornamentaly corrugations, by' making. the-curve at the outer side, not abouti the same center as the curve at the inner side, but about a center determinedby a shorter radius-,the horizontal curvature atthe outer side of'the corner being made With approxr; mately Vthe same radius as the horizontal curvature at the inner side of the corner. 'Itl will also be noticed that the curvature in' diagonal transverse plane,-that is, through partly'to define the corner, distinguishing it from the/mitering.
